Twin brothers from Kingfield, Francis Edgar Stanley and Freelan O. Stanley, were the first to develop a steam powered automobile. The "Stanley Steamer" was as fast or faster than the first gas-powered cars.

In 1906, a Stanley Steamer set the world record for the fastest mile at 28.2 seconds.

Ku Klux Klan membership reached an all-time high in Maine during the 1920s.

About 50,000 Mainers, or 6.2 percent of the total population of the state, were Klan members in 1924, actively protesting against non Anglo immigrants, particularly Franco-Americans, Italians, and Irish Catholics.

A national concern about traitors, spies, and subsersives led to immigrants being closely watched. This sentiment carried into Klan activities.

Mainers lost interest in the Klan rather quickly, although the bigoted attitudes that the group embodied persisted after its demise. In the South, where Klan members often targeted African-Americans, momentum was maintained much longer.
